黔中及邻区地裂缝特征及成因初析

The Features and Genesis of the Surface Fracturing in Central Guizhou and Adjecent Areas

本文根据黔中及邻区近年来,特别是1985年和1990年两次出现大面积地裂缝的灾情,形态及某些特征,着重论述了地裂缝的成因及其主要的相关因素,并提及了与地震的某些关系,指出了构造型地裂缝与地震的关系密切,两者均是活动断层最新活动表现。另外,对于不同类型的地裂缝,应采取不同的防治措施,以减轻地裂灾害。

According to the form and gedoical features of the surface fracturing happened in central Guizhou and adjecent areas in recent years, especially in 1985 and 1990,the genesis and relative factors of surface fracturing have been probed. The relationships between surface fracturing and earthquake have been studied and the study results indicate that the structure-type surface fracturing is closely related to earthquake and both of them are due to recent movement of active faults. Because the features and relative factors of different types of surface fracturing are different, the different measures of surface fracturing protction should be taken.
